Check for bad certs from Komodia / Superfish

For Superfish there is now an official
removal Utility from Lenovo.
I am not aware of any generic tool to remove the others. You need to
manually uninstall the software first and the certificate afterwards.

If you're interested in more technical background look
here. Filippo has
another test that is more user
friendly, but right now it doesn't detect as much as this one.
